The pump capacity and/or number of revolutions can be controlled by a
current signal. The current signal is connected between pin 3 and pin 4.
Pin 1 and pin 4 must also be connected.
The pump works at a pre-set capacity if:
Pin 5 and pin 4 are connected to each other. At the same time, pin 1
n
and pin 4 must also be connected to each other. The auxiliary
capacity is factory-preset to maximum capacity.
There is a connecting option for a 2-stage level switch with pre-warning
and limit stop.
